Answer:

y = 4x - 2

Step-by-step explanation:

First, let's find the slope of the equation. If you take a look at the table of values, as x goes up by 1, y goes up by 4. This means the slope is 4. To find the y-intercept, look where x = 0. When x = 0, y = -2.

In conclusion, the equation is:

y = 4x - 2

1.5^-2. how do i simplify that? the ^ means -2 is an exponant
hodyreva [135]
1.5 = 1 1/2 = 3/2
When there is a negative exponent, you find the reciprocal of the base, so therefore: 3/2 ^ -2 = 2/3 ^ 2
Then you square the numerator, then square the denominator: 2^2/3^2 = 4/9

Y is the midpoint of AB, The coordinates are A(-3,-7) and B(-1,1) What is the coordinate Y?
NISA [10]

The formla of a midpoint of AB:

M\left(\dfrac{x_A+x_B}{2},\ \dfrac{y_A+y_B}{2}\right)

We have A(-3, -7) and B(-1, 1). Substitute:

x_M=\dfrac{-3+(-1)}{2}=\dfrac{-4}{2}=-2\\\\y_M=\dfrac{-7+1}{2}=\dfrac{-6}{2}=-3

<h3>Answer: M(-2, -3)</h3>

The area of the rectangular faces of the box are shown . What is the volume of the box
Gnoma [55]
Label the 3 distinct sides of the box.  I arbitrarily chose the letters a, b and c.
Use the info about areas as follows:

ab=54 in^2
ac=90 in^2
bc=60 in^2

Here you have 3 equations in 3 unknowns (a, b and c), which is enough info to use to determine a, b and c.  Then the volume of the box is a*b*c.

Example:  bc = 90, but c = 60/b.  You could subst. 60/b for c in the 2nd and 3rd equation, which will eliminate c completely and leave you with 2 equations in 2 unknowns.

Continuing this procedure, I determined that a=9, b=6 and c=10.  Thus, the volume of the box is V = 9*6*10 = 540 cubic inches (answer)
